Conditions of Composting

REVIEW OF CONCEPT THUS FAR…

The effectiveness of the composting process is dependent upon the following environmental conditions present within the composting system:

1. Oxygen

2. Temperature

3. Moisture

4. Material Disturbance

5. Organic Matter

6. Size and Activity of Microbial Populations

What is the essential role of microorganisms in composting?

Composting is not a mysterious or complicated process. Natural recycling (composting) occurs on a continuous basis in the natural environment. Organic matter is metabolized by microorganisms and consumed by invertebrates. The resulting nutrients are returned to the soil to support plant growth.

What are the essential elements required by composting microorganisms?

The essential elements required are carbon, nitrogen, oxygen and moisture. If any of these elements are lacking, or if they are not provided in the proper proportion, the microorganisms will not flourish and will not provide adequate heat. 


 QUICK FACTS!

• Compost can capture and destroy 99.6% of industrial volatile organic chemicals (VOCs) in contaminated air!

• Disposing of food waste in a landfill contributes to global warming. Every metric dry ton of food that goes to a landfill may generate .25 metric tons of methane in the first 120 days. Thus, composting this food waste would reduce emissions by the equivalent of up to 6 metric tons of CO2.

        How can your compost pile turn to “bad” soil?

Too much water can cause the compost pile to become anaerobic and emit unbearable odors. When there is water shortage this can prevent the microorganisms from spreading. 

What are some different types of Fertilizers?

Organic: natural materials with little to no processing

Processed fertilizers: manufactured or extracted from natural materials often undergoes extensive processing

Organic fertilizers usually release nutrients slower than processed forms

Nutrient content in organic products is typically lower than processed forms

How long is a successful composting period?

The composting period is governed by a number of factors including, temperature, moisture, oxygen, particle size, the carbon-to-nitrogen ratio and the degree of turning involved. Generally, effective management of these factors will accelerate the composting process.
